Sealmaster 2-3/16"-ID 4-BOLT TRB FLANGE UNITS SEAR RFB-203
Sealmaster® RPB mounted tapered roller bearings are a dimensionally interchangeable upgrade from competitive Type E bearings. The exclusive features include unitized replaceable inserts, self aligning capability, split housing and the Sealmaster® alignment pin which provides for a direct path for lubrication into the bearing and helps prevent outer ring rotation. The Sealmaster® RPB is available with two traditional setscrew locking collars for easy installation. The felt seal with flinger provides a good balance between contaminant entry, grease retention and friction. Depending on application requirements, these bearings are available in both inch and metric with a wide variety of housing, sealing and lubrication options.

The McGill® CAMROL® full complement needle bearings feature black oxide treated bearing steel. They are available in two basic mounting styles for use in mechanical automation or linear motion applications. Our basic features each contribute to superior performance. The LUBRIDISC® seal option helps prevent metal to metal contact within the bearing. It also provides a barrier for containment entry and blowout protection when relubricating. These bearings are available with several dimensional choices. The seal options and combinations provide a specific solution for each application. Within the following section you can learn more about these features and how they can be applied to your application.
